COMBINED FIREPLACE HEATER AND FURNACE.

SPECIFICATION forming part of Letters Patent No. 506,796, dated October17, 1893.

Application filed March 30, 1893- Serial No. 468,385. (No model.)

To aZZ whom it may concern.-

Be it known that I, ELBERT SEVERE ROGERS, a citizen of the UnitedStates, residing at Knoxville, in the county of Knox and State ofTennessee, have invented a new and useful Combined Fireplace Heater andFurnace, of which the following is a specification.

My invention relates to that class of fireplace heaters constructed andadapted to heat distant rooms or apartments.

The objects of my invention are to provide a heater of cheap and simpleconstruction; composed of few parts; readily formed and assembled andreplaced when worn out; to provide for the admission of a continualcurrent of cold pure air and adequate heating of the same; a conductionthereof to the various points of distribution when desired; to providemeans for confining the air to the room in which the furnace is located;and to provide accessories in the way of dampers and their operatingmediums, all being under the control of a person in the room wherein theheater or furnace is located, for controlling the distribution of theheat to the rooms above.

With these and various other objects in view the invention consists incertain features of construction hereinafter specified and particularlypointed out in the claims.

Referring to the drawings:-Figure 1 is a vertical longitudinalsectional-view of a chimney and portions of the three floors of abuilding, a furnace constructed in accordance with my invention beinglocated therein. Fig. 2 is adetail in perspective of the furnace. Fig. 3is a front elevation thereof.

Like numerals of reference indicate like parts in all the figures of thedrawings.

For the purpose of illustration, I have shown a chimney 1, having anopening 2, at its front, the same being intended to communicate withopposite rooms upon the same or first floor, and above the first floor Ihave shown two additional floors, designated as 3 and 4, though it willbe apparent that, as will hereinafter appear, the heater may be employedin connection with either a one or a two-story house, or a house with agreater number of floors than three if desired, the principle being thesame throughout. Located in the chimney on a level with the bottom ofthe openings 2 is the base 5, upon which the furnace is to be seated.This base may be any suitable support desired, as for instance, a metaldiaphragm suitably supported in the masonry of the chimney, and the sameis provided with a central opening 6, with which communicates the upperend of a cold air-pipe 7, that may lead from the exterior of thebuilding, and in localities where there are bad sanitary conditions, itmay lead from the top of the house or any other suitable point of freshairsupply. At a point above the openings 2 in the chimney there islocated a horizontal diaphragm or metal plate 8, the same having in thepresent instance a pair of openings 9 and 10, the former being providedwith a sliding damper 11, which is operated through the medium of ahandle or rod 12' which projects through an opening in thechimney-breast into the room in which the furnace opens. The remainingopening is to accommodate the smoke-pipe 13 which projects upward froman opening madein the shellofthefurnacel-i. Abovethefloor3,atoppositesides of the chimney, register-box receiving openings 15, are formed,and immediately above these a second horizontal diaphragm or plate 16,is seated in the masonry, the same having in the present instance a pairof openings 17 and 18. The third floor 4, likewise has register-boxopenings 19, at opposite sides of the chimney, and above the same islocated a third diaphragm 20, in this instance having a single opening21 in line with the openings 18 and 10 of the diaphragms below. If otherfloors are above the third floor of course the third floor will have anopening similar to the openings 11 and 17 of the diaphragms 8 and 16,the same being provided with a damper. In the present instance, however,as the third floor is the last one to be heated the damper and itsopening are omitted.

From the smoke-pipe 13, which terminates immediately above the diaphragm8, there extends a suitable flue 22, preferably formed of tiling, thesame leading to the upper end of the chimney through the openings 18 and21.

The shell or furnace is provided with a suitable lining 23 of firebrick,a grate 24, and openings 25 and 26, the former being above the latter,and the latter being directly in the back-wall above the line offire-brick; and pivotally mounted therein is a damper 27, the

shaft of which is connected with an operatingrod 28, which projectsthrough the chimneybreast above the opening 2. A semicircular perforateguard-plate -29, is pivoted as at 30, in the opening 26, and serves toprevent coal when fed to the grate passing through the opening and yetat the same time being perforate does not obstruct to any materialextent said opening.

In rear of the furnace below the opening 26 a steel drum 31 is located,and the same communicates at its center with the opening 26 through themedium of a pipe 32. In rear of this drum 31 and the pipe 32 there islocated an inclined series of drums, in this instance threein number,and designated as 33, 34, and 35. The drum 31 communicates with theseries and the series with each other through pairs of short side-pipes36. The drums are preferably constructed of steel, that is, theirbody-portions are, while their heads 37 are of cast-metal. The rearsides of the drums it will be seen are provided with hand-holes 38having suitable covers, which when removed permit access to the drumsfor the purpose of clearing them of soot. From the upper drum 35 at thecenter thereof there leads a pipe 39 which communicates with thesmoke-pipe 13 immediately above the damper 27. Just below the diaphragm8 the opposite sides of the chimney are provided with register openings40.

The operation of the combined heater and furnace is as follows: Whenstarting the fire the damper 27 is opened so that a direct draft issecured. When sufficiently kindled or started the damper 27 is closedand the products of combustion then pass through the opening 26 andthrough the series of heatingdrums, and is finally directed into thesmokepipe or flue. Before reaching the smoke-pipe or flue its caloricqualities are for the most part absorbed, and the cold fresh aircirculating around the various pipes and drums becomes heated, and ifthe damper, 11 is closed will be discharged through the lower registerbox 40 so that the heat is confined to the first floor. If, however, itis desired to heat the second fioor also, the damper 11 is opened andthe heat ascends to the diaphragm 16, being discharged through theregister boxes 15 of the second floor. If it is also desired to heat thethird floor the damper 17 is opened and the heat may be dischargedthrough the registerboxes 19. The drums 31, 33, 34, and 35 may be givenany relative proportion desired, but I prefer constructing the firstdrum 31 somewhat greater in diameter than the remaining drums 33, 34,and 35 of the series.

From the foregoing description in connection with the accompanyingdrawings it will be seen that l have provided a combined furnace andfireplace heater, the same being composed of few parts, readilymanufactured, assembled and replaced, and adapted to be employed forheating one or a series of floors as may be desired, the said furnacehaving the external appearance of an ordinary open fireplace-heater.

Having described my invention, what I claim isg 1. The combination witha chimney having an opening, a diaphragm over the opening, aregister-box over the opening, of a furnaceshell arranged in rear of theopening within the chimney, a smoke-pipe leading from the upper end ofthe shell, a damper therein, a series of hollow drums arranged in rearand in a series extending over the shell, a pipe leading from the backof the shell to the first drum, and pipes leading from the first drum tothe second, and so on throughout the series and from the upper drum tothe smoke-pipe above the damper therein, substantially as specified.

2. The combination with the shell of the furnace havingthe grate, andopenings at the upper end of the shell and immediately above the grate,a smoke-pipe connected with the upper opening, heat-radiating devicesconnected with the rear opening, and a perforate guard pivoted in thelower opening, substantially as specified.

3. The combination with a chimney having an opening, aperforateddiaphragm arranged in the chimney above the opening, a damper thereover,a rod for operating the same, a lower diaphragm having a perforationarranged below the opening, a cold-air pipecommunicating therewith, of afurnace-shell located in rear of the opening and supported upon thelower diaphragm, a smoke-pipe leading from the upper side of the shelland having a damper therein, and a series of cylinders arranged in rearof the shell communicating with each other, the rear opening of theshell, and the smoke-pipe above its damper, substantially as specified.

4. In a combined fireplace heater and furnace, the fireplace havingopenings 25 and 26, and the grate 24, and the damper 27 to close theopening 25, combined with the pipe 32 connected thereto, the drum 31,the pipe 36, the drums 33, 34, and 35 connected together andcommunicating with each other, and the pipe 39 connecting the last drum35 of the se-' ries with the chimney above the damper 27, substantiallyas described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signaturein the presence of two witnesses.

ELBERT SEVERE ROGERS.
